To all whom t may concern Be.it known that I, FRANK MARZAK, a citizen of Poland, residing at College Point, county of Queens, and State of New York, and I, STANLEY DUsEK, a citizen of the United States of America, residing at College Point, county of Queens, and State of New York, have invented certain new and useful Improvements in Aeroplane Landing-Wheels, of which the following is a specification.

This invention relates to improvements in aeroplane landing wheels,` and has as its special object the provision of means whereby an aeroplane or like type of flying machine is able to make a resilient contact with the surface upon which it rests preliminary to flying or at the time of alighting. j

This and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is an enlarged sectional view, taken substantially through the center of a landing wheel, made in accordance vwith the invention.

Fig. 2 is a transverse sectional view, taken on line 2-2 of Fig. 1.

As'shown on the drawing the wheel has an outer band or tire 30, surrounding a plurality of spring cylinders 3l, arranged in a circular row, so that the cylinders contact the band and each other and are heldto the band by rivets 32, the sides being connected by rivets 33 one with the next adjacent.

Arranged interiorly of the outer row is a second row of similar but larger and somewhat longer spring cylinders 35, connected with the cylinders of the outer row by rivets 36, and connected by other rivets 37.

Disposed within the row of cylinders 35 is still another row of cylinders 38, relatively smaller in diameter but exceeding the same in length, these cylinders being connected with the cylinders 35 by rivets 40, and with each other by rivets 41, the inner row of spring cylinders being engaged with a tubular sleeve 44, forming the internal structure of the wheel.

The sleeve 44 is provided with a flange 45 adjacent each end and abutting the ends of the inner row of tubular elements. Each ange, as shown, is provided with outwardly extending portions 46 and each portion 46 engages the ends of two adjacent ytubular elements and extends beyond the longitudinal centers thereof. The flanges 45. and their extending parts 46 constitute a durable hub construction for the wheel while they do not impede in any way its resiliency. This construction thereby will greatly facilitate the difficulties experienced during 'the landing operation of the aeroplane so that shocks and jars are not imparted to the frame and other parts of the airship which must be considered an important improvement over the existing art resulting in a great saving' of material and preventing injuries and in some instances even death to the operator.

The outwardly extending ends of the sleeve 44 have formed with them angular flanges 50,r having outer beveled surfaces 51, contactable with which are coned disks 52, engaged on their outsides by the side coverings 55, the same being made of leather -or of a suitable textile fabric, and held in place by outer cone-,elements 56, clamped by collars 57.

Engaged kwith the extending ends of the sleeve held in position by the flanged ends 58, are bushings 59, made of an anti-fric tional material, and suited to be closely received within the bore of the sleeve 44.

An oiler for containing lubricants is entered into one of the cylindrical elements 38, same having its inner end engageable within the recess formed between the bushings 59.

The outer edges of the coverings are received within bands 62, closely litted within the tire element 30, and held therein by interior bands 64, engaged by fixed studs or rivets 65, the same being enterable through openings 66, having angularly turned slots 67, receptive of the stems of the studs 65, which are provided with heads. forming in effect an adaption of the well known form of bayonet joint whereby the band may be engaged in position within the tread 30, holding the side coverings 55 in a taut extended position. It isclear that the coverings must be secured to the band 30 and the rivets and rings 64 placed in position before the elements 56 and collars 57 are put in place to secure the inner edges of the coverings 55. j

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is

In an aeroplane landing wheel, the 'combination with a Central tubular sleeve, a pluoured loircurnj zioent to the outer row of said rality of resilient cylindrical elements al cylindrical elements, and mperforate Covranged in rows about said sleeve, a Hang@ erings seouredto said band extending over adjacent each end of said sleeve and abntthe sides yof the wheel covering the ends of 5 ting the ends of the inner row of said oysaid Cylindrical elements and engaged by 15 lindricztl elements, outwardly extending porsaid sleeve. tions on each iange, each. of said portions In testimony whereoi` we have affixed our engaging the ends of two adjacent cylinsignatures. n drioal elements and extending beyond `the y FRANK MARZAK.
